Fig. 12 is a detail transverse sectional view illustrating another modification of the invention in which the holder is corrugated.

Referring particularly to the form of the invention illustrated in Figs. 1 to 6, inclusive, of the drawings, the bookbinder is provided with a cover element l composed of a back 2 and hinged leaves 3 preferably made of board or other suitable stiff material and preferably covered at the inner and outer faces with cloth, leatherette or other suitablematerial. The back is preferably composed of a stiff strip 4 of board or other suitable material and is faced with a piece 5 of fabric or other suitable material interposed between the strip 4 and a holder 13 and extended beyond the same and secured by adhesive or other suitable material to the inner faces of the hinged leaves. The outer covering? of the hinged leaves 3 is preferably extended across the strip 4 in the formation of the back of the cover element and is secured by adhesive material or other suitable means tothe strip 4. The cover element I may however be made in any other desired manner and may be variously ornamented as will be readily understood.

The holder 6 is preferably of double channel formation to provide a front channel 8 and a rear channel 9. The holder is designed to be stamped or otherwise formed from a single substantially oblong piece of sheet metal which is bent at right angles at spaced points to provide parallel front flanges l0 and a connecting web H. The metal of the flanges Ill is then folded back upon the flanges at each side of the holder and extended rearwardly beyond the web H to provide spaced parallel rearwardly extending flanges l2 which form the side walls of the rear channel 9. The rear flanges l2, are fitted against the back of the cover element and may be secured to the stiff vstrip by tubular rivets !3, as

clearlyillustrated in Fig. 2 of the drawings, but

any other suitable fastening. means may of course be employed. The rivets l3 pierce the strip 4 and terminate short of the outer face of the cover element. 'The fabric member 5 assists in securing the holder to the cover element as the fabric element extends across the strip 4 between the same and the holder and is secured to the hinged leaves of the cover element.

The front channel of the holder is adapted to receiveone or more books which are retained in the front channel by spring clips Hi located at the upper and lower ends of the holder and constructed of spring steel wire or other suitable material and composed of front and rear legs 15 and I6 and a curved connecting portion 11. The resilient book engaging clips l i which may be of any desired number and which are laterally adjustable on the end portions of the holder have their frontlegs located in the front channel 8 and their rear legs arranged in the rear channel 9. The front leg l5 of each book engaging clip is straight and is designed to be of greater length than the rear leg [5 for engaging books of different sizes and regardless of the thickness of a book it is adapted to lie flat against the bindingof the book in parallelism with the web ll of the holder and it is provided at its free end with a relatively large circular loop l8 forming an eye adapted to be readily grasped between the fingers to facilitate the removal of the spring clips from the holder. Also the eye formed by the loop i3 is adapted to be readily engaged by a key L3 or other instrument to facilitate removal of the spring clips and the terminal loop I8 enables the spring clips to be readily engaged with a book without liability of injuring the leaves or binding thereof. The rear leg is provided with an angular bend 20 which fits against the rear face of the web H of the holder when the clip is in position on the holder and it' forms a fulcrum and it coacts with the curved connecting portion of the clip to enable the front leg to be arranged in parallelism with the web portion of the holder when the said front leg is in engagement with the binding of a book regardless of the thickness of the book. The major portion of the rear leg I8 is straight and is arranged at an acute angle to the straight front leg i5, and its free terminal bears against and fulcrums onthe rear face of the holder. The curved connecting portion ll of v the clip is resilient and forms with the front and rear legs a tapering spring loop which is adapted to adjust itself automatically to the thickness of a book with the straight front leg lying flat against the book. The resilient connecting portion of the loop and the fulcruming of the free end of the rear leg against the holder permit the front leg to maintain itself in parallelism with the holder and lie flat against a book at different distances from the holder so that it will always lie flat against a book regardless of the thickness of the same. The rear leg is provided at its free end with a substantially circular loop 2| of a size to lierwithin the rear channel of theholder. The spring clips .may be arranged at either or both ends of the holder for temporary or permanent binding and, when arranged at one end only at either the top or bottom of the holder, books, catalogues, pamphlets, leaflets and the like of different sizes may be readily placed in and removed from the binder by simply engaging them with and disengaging them from the front legs of the clips without removing the clips from the holder.

The spring clips are moved lengthwise of the holder to engage them with and disengage them from the holder and they are retained in'position on the holder by closure members 22 constructed of sheet metal or other suitable material and consisting of a substantially L-shaped plate provided with side flanges 23 and having spaced longitudinally extending resilient ears 24 formed integral with and extending from the flanges 23 and arranged within the rear channel 9 and fittedflat against the inner faces of the side walls or flanges i 2 of thelrear channel. The L-shaped plate of the closure member is composed of wings 25 and 26; the wing 25 fits between'the rearwardly extending flanges l2 of the holder and the other wing 26 extends across the end of the holder and with the side flanges 23 confines the spring clips 14 on the holder. The side flanges of the closure member extend from the wing 25 and abut against the front flanges i of the holder.

The resilient arms 24 of the closure member are provided at their inner ends with laterally extending lugs 2'! which project into slots 28 in the side walls or flanges l2 of the rear channel 9 of the holder, as clearly illustrated in Fig. 3 of the drawings. The lugs 21 are shouldered at one end at 29 and are beveled at 30 to facilitate the ready insertion of the arms 24 into the rear channel and to provide a locking engagement between the lugs 21 and the outer end walls of the slots;28 when the closure members are in their locked position. 1

. The shoulders 29 prevent the closure members from being withdrawn from the rear channel of the holder until the lugs 21 are disengaged from the slots 28. When the lugs 21 are pressed in: wardly out of engagement with the slots 28. the

closure me'mber may be readily withdrawnfrom' projecting fingers 32 whichare of a size toextend through the slots 28 and force the lugs 21 in.-

wardlyout-of engagement with the slots, as clearlyillustrated in Fig. 6 of the drawings. Whenthe lugs 27 are moved inwardly out of engagement with the slots 28 as'illustrated in Fig. 6the closure member may be readily withdrawn from the holder and removed therefrom as indicated .in dottecllinesin Fig. 6 of the drawing I This exposes the spring clips and enables the latter to be readily removed and replaced as required,

In Fig. 1 of the drawings a single book 33 which may consist of a magazine or catalogue orthe like is arranged in the holder and completely fills the same and is of a length substantially equal to the length of the holderp In Fig. '7 a plurality of books 34 are shown arranged within the holder 35 and of a length less than the length of the holder. The holder 35 which is of substantially the. same construction as that heretofore described is shown providedwith a plurality of spring clips at each end.; The spring clips may be of any desired number. andare retained in place by closure members 36 constructed the same heretofore explained in 1 connection with the Y holder 6.

In Figs. 9 to 11, inclusiva'of the drawings is illustrated a holder 40 of channel formation con sistingv of rearwardly extending flanges '4 I and a 1 connecting web 42, the frontchanneloithe holders heretofore described beingomitted. The holder 50 is relatively wide and is particularly adapted for holding a large number of books of the smaller type such as pamphlets. ,Thepamphlets or booklets are secured on the holder by spring clips l4 which are retained inpositioned on the holder by closure members :43 constructed substantially the same asthe closure members heretofore described with the exception that the resilient arms 44 are providedwith lugs 45 "beveled at each end to enable them to be readily disengaged from the slots 46- without the use of a key or other instrument. The beveled lugs 45 will enable the closure members 43 to be readily applied to and removed from the holder 40.

In Figure 12 of the drawings is illustrated another modification of the invention in which the holder.

the channel.

holder 41 is corrugated, forming a plurality of channels and apices at the front and back of the holder to space the spring clips and yet allow lateral movement or adjustment of the spring clips on the holder. The channels and apices at the front of the holder permit books to be arranged instaggered relation with the thicker back portions arranged alternately in the channels 48 and'on the apices 49 at the front of the By staggering the backs of the books in this manner, more books may be placed in the bookbinder than islpossible where the holder has a continuous flat surface to receive the books. The frontlegs of the spring clips lie flat against 7 the books while the rear legs of the spring clips are located at the channels 49 and apices 50 formed by the corrugations at the back of the holder.
